- asking for feedback
    - how is the clint system design?
        - fine, no problems
    - how is the design doc? (prose, more graphics?)
        - add example (either as graphic and/or text)
    - mem_op extended: trap_op
    - mret as reverse traps: pc to return address stored in mepc
        - fine (hopefully no problems)
    - exec_op extended: clint_op (exc/int vec)
        - need to measure complexity of extensions
